This is a replacement main rotor damper set for the Align 500
line of helicopters. The dampers fit over the feathering shaft and into
the main rotor housing and provide a firm but flexible support of the
feathering shaft and main blades while allowing the rotor assembly to
"flap" normally which reduces vibration in the rotor head assembly.
Firmer dampers generally results in a more responsive feel to the
helicopter while softer ones provide a more stable feel.
